Containerization operation and maintenance method and system for stateful service

The invention provides a containerization operation and maintenance method and system for stateful service, and relates to the technical field of containerization application. The method comprises the following steps: firstly, configuring data in an etcd, and writing dynamic configuration of stateful service into the etcd; and then, constructing a service mirror image in a K8S format through dockefile, reading configuration items from an etcd storage system, and adding the configuration items into an initialization script, so that a container under the management of a K8S platform can automatically generate corresponding configuration every time the container is started. Then, a K8S platform is used for starting service to execute the initialization script, and a configuration file is dynamically generated; and finally, on the basis of the configuration file, the operation state of the service is managed through supervisor, and operation and maintenance management of the stateful service is realized.
